Anne Mitchell, a Texas nurse, is being indicted and threatened with 10 years in prison for informing state regulators that a doctor at her rural hospital was practicing bad medicine. Mitchell is scheduled to stand trial in state court for "misuse of official information," a third-degree felony in Texas. The prosecutor said he would show that Mitchell had a history of making "inflammatory" statements about Rolando G. Arafiles Jr., MD, and intended to damage his reputation when she reported him last April to the Texas Medical Board, which licenses and disciplines doctors.
